The U.S. government is selling more of its shares in insurer American International Group Inc. in a move that should decrease its holdings below a majority stake for the first time since the $182 billion bailout in 2008. AIG said Sunday, Sept. 9, 2012 that the Treasury Department was selling $18 billion worth of AIG common shares. The department will grant underwriters a 30-day option to purchase $2.7 billion more if there is demand. The shares will be sold to institutional investors. (AP Photo/Richard Drew)
